According to an alert from BART, there will be no train service between San Francisco and the East Bay for at least a half an hour around Noon on Tuesday due to an obstruction on the tracks.

No word yet on what is blocking the tracks or where, but we'll be sure to update when service resumes.

Update: Hey, that was quick. BART says service is resuming right on schedule around 12:30 p.m., but you can expect some residual delays:
